Water dripping through the HVAC. Drain hose is NOT clogged.
Hi!
Recently I started noticing a moldy odor coming from my car so I took out the passenger side floor mat and it was very wet underneath. I took the carpet off and noticed the HVAC was dripping (not a constant stream) water. I read like a million of threads in here and other forums and 99% of them were caused by clogged drain hoses. Happy that I had found a solution, quickly went to my car again and disconnected the black drain hose connected to the HVAC into the firewall, and blew the hose and to my surprise it was not clogged and perfectly clean on the inside. Then I inserted a metal wire through the HVAC hole and twisted it a bit. Nothing. It wasn't clogged either. I turned the AC on for a few minutes and noticed the dripping was coming from the HVAC and, when I turned the car or the AC off, the water from the AC would drain normally like it should through the drain hose to the ground underneath the car. So, to recap: HVAC nor drain hose are clogged. It drains the water normally like it should. However the HVAC still drips water when the AC is on. Any help will be really appreciated!
